These primary barriers to fungal infection include intact skin , naturally occurring long - chain unsaturated fatty acids , and competition with normal bacterial flora 这些抵抗真菌感染的主要屏障包括完整的皮肤,能产生不饱和的长链脂肪酸,与正常菌群的竞争等等。
But it further inhibited the low affinity system . 1 . 3 effect of k + channel inhibitor on the na + content nem ( 3 mmol / l ) is a specific inhibitor of the high affinity k + uptake system 另一个是不饱和的低亲和k ~ +吸收系统,其一级反应常数k为1 . 1 ,说明nacl胁迫浓度的增加进一步抑制了碱蓬的低亲和k ~ +吸收系统。
The primary structure is composed of a circle comprised of 15 kinds of molecules , while the 4th and 5th sites of carbon are intergrated with a circle of unsaturated oxygen , and a lipid chian is ligated at the 13th site of carbon 其骨架由一个15元环组成,在环的碳4和碳5位又与一个不饱和的4元氧环相联,在碳十三位还带一个酯基侧链。
